    Study Notes

    Color Perception

    • Color is a perception created by our brain when it receives signals from our eyes.
    • Our eyes have receptor cells called cones and rods that stimulate when they receive light.

    Light and Spectroscopy

    • Light is formed by different wavelengths, which create the visible spectrum.
    • The visible spectrum was discovered by Newton in 1655 when he passed a small beam of light through a prism.
    • The visible spectrum ranges from 390 to 750 nanometers, while longer and shorter wavelengths are invisible to our eyes.

    Color Theory

    • There are two types of colors: light colors and pigment colors.
    • Light colors are created through additive mixing and have three primaries: red, green, and blue (RGB).
    • When all light colors are combined, white is produced, and when all are absent, black is produced.

    Pigment Colors

    • Pigment colors are created through subtractive synthesis and have three primaries: cyan, magenta, and yellow.
    • When all pigment colors are combined, black is produced, and when all are absent, white is produced.

    Color Harmonies

    • When two primary colors are mixed, secondary colors are created.
    • When a primary color is mixed with a secondary color, tertiary colors are created.
    • A secondary color forms with its primary complementary color, which creates high contrast.

    Artistic Applications

    • Artists have used color harmonies and complementary colors throughout history, such as the Impressionist movement in France.
    • Famous artists like Vincent van Gogh, Henri Matisse, and Fernando Zóbel have utilized color theory in their works.

    Color Properties

    • Hue refers to the color itself (e.g., blue, green, yellow).
    • Saturation refers to the intensity or purity of the color.
    • Luminosity refers to the brightness or darkness of the color.
    • Tone refers to the combination of hue and luminosity.
    • Shade refers to the darker version of a color, and tint refers to the lighter version.

    Color Perception

    • Our brain creates color perception from signals received from our eyes.
    • Eyes have receptor cells (cones and rods) that stimulate when receiving light.

    Light and Spectroscopy

    • Different wavelengths of light form the visible spectrum.
    • Newton discovered the visible spectrum in 1655 by passing a small beam of light through a prism.
    • Visible spectrum ranges from 390 to 750 nanometers, while longer and shorter wavelengths are invisible.

    Color Theory

    • There are two types of colors: light colors (created through additive mixing) and pigment colors (created through subtractive synthesis).
    • Light colors have three primaries: red, green, and blue (RGB).
    • Combining all light colors produces white, while absenting all light colors produces black.

    Pigment Colors

    • Pigment colors have three primaries: cyan, magenta, and yellow.
    • Combining all pigment colors produces black, while absenting all pigment colors produces white.

    Color Harmonies

    • Mixing two primary colors creates secondary colors.
    • Mixing a primary color with a secondary color creates tertiary colors.
    • Secondary color forms with its primary complementary color, creating high contrast.

    Artistic Applications

    • Artists have used color harmonies and complementary colors throughout history, including the Impressionist movement in France.
